Linux Administrator

We are looking for a Linux Administrator to join our HFT team. This role manages and optimizes bare-metal Linux servers that power our trading systems. It’s not regular IT infrastructure—here, microseconds matter, and the focus is on performance tuning and stability. You’ll work closely with systems connected directly to stock exchanges, handling real-time market data and order flow. Stability and low latency during live market hours are extremely critical. This is a high-ownership role. During market hours, the systems must be extremely stable. You’ll be involved in monitoring, troubleshooting, and resolving issues quickly because downtime directly impacts trading. You’ll work very closely with developers, quants, and trading teams to optimize infrastructure performance and support new strategy deployments.

Responsibilities
• Perform regular health checks and monitoring of overall infrastructure
• Configure, deploy, and manage Linux services on bare-metal servers
• Manage and maintain SLURM clusters and distributed storage system
• Handle networking setup including routing, VLANs, bonding, and NIC tuning
• Server provisioning, OS installation, and infrastructure standardization
• Manage drivers, packages, kernel modules, and firmware updates
• Perform performance tuning, overclocking, and low-latency optimizations
